I'm not sure if this is the right place to ask this, but how do you measure your tank levels? For plastic tanks, I've read about capacitive and ultrasound sensors (i would like to avoid to create a hole in the tank), but since i don't do well with electronics, I'm quite confused.
Is there any ready-to-go kit or anything like that?
Once i have something that i can plug to my rpi5, no matter if nmea, i2c, 1w... I can handle.
